Sanderson's is going to be your best bet...they are actually for the Cleveland but they will work as they send a very heavy duty copper gasket that reduces the port size down to the 351m\400. You should order them with the Ceramic coating both inside and out. They make a very hi quality product in my opinion!!! They are actually a Shorty style of header and I don't know of anyone who makes a full-length header that will fit a hiboy that is 4x4. Now..I'll Tell you What i would Do if i had it TOO DO OVER. KEEP YOUR MONEY...You don't NEED no Stinking Headders!!!!Clean up your heads , and deburr your existing exhaust manifolds.....And then you won't have to constantly be jacking with those Damn Loose Bolts in the head. For the 500 or so you'll spend on headders you can add a hi-torque stater(199) from summit , and put 300 towards a new exhaust system for your truck....just my opinion( then and Now)...fd

I guess I need to learn some new stuff here. I never knew Ford made a HighBoy with the 351M in it. The 351M did not start untill 77 1/2 and they started makeing the trucks in the LowBoy Fashion. If its a HighBoy then It came with an FE motor. So even if its a transplanted 351M the LowBoy Headers should work.

I guess you do bigbully because F26HE says it a f-250 4x4 w/351m 2 bbl manufacured date 10/76 sold as a 77 out of mahwah n.j. . It has power assist steering / fuel tank behind seat / divorced np205 435 4 spd / frame measurement is the same all the way through and the boxed cross member at front frame horns . the leaf springs are 2.5 in rear & 3 inches in front . Am I missing something?
